Liquid crystal (LC) shape‐amphiphiles with a disc tethered to a fullerene have been intensely studied for the application in photovoltaics, and helical nanosegregation of C₆₀ has been claimed around the π‐stacking disks based on X‐ray results. The most promising materials reported to date have been resynthesized and studied comprehensively by XRS, density measurements, modelling, and electron density reconstruction. In contrast to previous reports, the results indicate that metal phthalocyanine−fullerene mesogens pack in lamellar columnar phases with p2gm symmetry. Fullerenes assemble in layers and are flanked by phthalocyanine columns, thus explaining the balanced charge carrier mobility of electrons and holes. Such variable donor−acceptor structures are promising for organic electronic applications.

金属酞菁-富勒烯染料：有希望的层状柱状供体-受体液晶相。

带有束缚在富勒烯上的圆盘的液晶（LC）形状两亲物已被广泛研究用于光伏中，基于X射线结果，C _60的螺旋纳米偏析被认为在π堆积盘周围。迄今为止报道的最有前途的材料已经通过XRS，密度测量，建模和电子密度重构进行了重新合成和综合研究。与以前的报告相比，结果表明金属酞菁-富勒烯介晶堆积在具有p2gm对称性的层状柱状相中。富勒烯分层组装，并被酞菁柱作为侧翼，从而解释了电子和空穴的平衡载流子迁移率。这种可变的供体-受体结构有望用于有机电子应用。
